Times Cited Count：1 Percentile：12.16(Materials Science, Multidisciplinary)We have developed an anomalous small-angle X-ray scattering (ASAXS) diffractometer in SPring-8 to investigate irradiation-induced nanostructural change in ion-beam irradiated stainless steel. A thermally-aged MA956 stainless steel sample displays power-law scattering that follows the Porod law at the magnitude of scattering vector, Q, below 0.5 nm
and an overlapped shoulder around 0.7 nm. After the ion-beam irradiation, the intensity of the shoulder remained unchanged, whereas that of the power-law scattering nearly doubled. This result indicates that none of the structural parameters of the Cr-rich nanoprecipitates, such as the number density, size, and interface roughness, were changed by the irradiation.

Times Cited Count：5 Percentile：22.94(Physics, Applied)Performance degradation and immediate recovery of a-Si/a-SiGe/a-SiGe triple-junction solar cells due to irradiation of silicon ions, electrons, and protons are investigated. Significant recovery is always observed independent of radiation species and temperature. It is shown that the characteristic time, which is obtained by analyzing the short-circuit current annealing behavior, is an important parameter for practical applications in space. In addition, the radiation degradation mechanism is discussed by analyzing the energy loss process of incident particles (ionizing energy loss: IEL, and non-ionizing energy loss: NIEL) and their relative damage factors. It is determined that ionizing dose is the primarily parameter for electron degradation whereas displacement damage dose is the primarily parameter for proton degradation. The impact of "radiation quality effect" has to be considered to understand the degradation due to Si ion irradiation.

This document presents radiation resistivity of various polymeric materials with collected data tables that are the candidate materials to be used in the High Intensity Proton Accelerator Facility Project, J-PARC, which is to produce MW-class high power proton beams. The effect of radiation damage and deterioration by loss-beam or secondary particle beam influences the performance and the reliability of various instruments. The radiation damage consists of mechanical property, electrical property and gas-evolution property, and these properties depend entirely upon the kind of radiation, energy and dose intensity. The first part of this document methodically introduces the general feature of polymer and its radiation-induced deterioration mechanisms, and the second part of the document shows the compiled data for irradiation effects of polymeric materials. The sources of the data are the published reports from the worldwide references.
